7. I would have to see the exchange.

As you posted, a jig is a type of dance. I was born in Charleston, SC and the farthest north I have ever lived was just inside the NC state line. I have never heard 'jigaboo' shortened to 'jig'. Not that it can't happen, but I think I have probably heard every single horrid, racist term for a black person in my 48 years in the South.

The woman might have been racist or thought she was being cute, but I would imagine that Barack Obama is so far above that sort of thing that he just took it in stride and kept right on rolling along. If she was trying to take a shot at him, I would think she failed miserably.
